REAMER DRILL FOR WELL BORING.
Application filed February 4, 1928. Serial No. 251,825.
My invention has relation to an improvement in reamer drills for boring wells or the like and in such connection it relates more particularly to the construction and arrangement of the drill.
My invention contemplates the provision of a drill which is provided with means for retaining its forked portions in contracted position while the drill is being lowered through the well casing and yet permit the expansion of the forked portions after the drill has reached its operative position for drilling.
My a 'iparatus is simple, yet positive and eflicient in operation, of relatively few parts, strong and durable in construction, and easily and cheaply manufactured.
The nature and scope of my invention will be more fully understood from the following description taken in connection with the accompanying drawings forming part hereof, in which- Figure 1 is a side elevational View of a drill and reamer embodying my invention, 'he surrounding casing being shown in section, and the drill projecting beyond the lower end of said casing.
Figure 2 is a side view of my drill and reanier.
Figure 3 is a view similar to Fig. 1 but illustrating the drill being lowered into the casing.
Figure 4 is an end elevational view of Fig. 1.
Figure is a cross-sectional view taken on the line 5-5 of Fig. 3.
Figure 6 is a cross-sectional view taken on the line 6-6 of Fig. 1.
Referring to the drawings 1 represents the casing which is in sections united together by couplings 2 screwed on the exterior of meeting ends of sections 1. Within the casing 1 the drill is adapted to be lowered, said drill having a screw or other connecting upper end 3 fitting into a sectional drill rod.
The main body 4: of the drill is formed of tool steel or similar spring metal and its lower or drilling end is divided into two forks 5. These forks 5 each have a main body portion 6 which is flattened, the body portions of the respective forks being contiguous to and riding over each other. The width of each fiat body portion is slightly less than the diameter of the enclosing casing, so that when both forks are drawn upward in the casing the fiat body of one fork lies upon and coincides in extent with the flat body of the other fork as clearly shown in Fig. 3.
Each drill fork 5 has a groove 9 through which the mud or earth or rock may pass upward as the drill advances. This groove 9 of each fork 5 is what is termed a mud groove and both grooves 9 terminate at their upper ends in the recess 10 cut into the drill body 4 to form the forks 5 of the drill. This drill body 4 is slightly flattened (see Fig. 1) on two faces to form a continuation of the space or channel through which the mud or excavated matter may pass upward into the cas- To permit the drill being lowered through the casing, the forks 5 are sprung together and a pin 11 inserted in the holes 12. This reduces the point of the drill 6 to a size to permit its passage downward through the casing 1. When in position for operation and the drill is rotated, this pin shears at the,
point 13 letting the forks spring apart to their full diameter.
Having thus described my invention, what I claim as new is I In a device of the character described, the combination with a drill adapted to be lowered into a well casing and having its main body recessed to form two forks, each of said forks having a flattened body, of means for holding said flattened bodies in contact with each other while said drill is being lowered through said casing and permitting said forks to spring apart when in operative position for drilling, said means comprising a pin projecting transversely through said fiattened bodies and adapted to be sheared when said drill is rotated, allowing said forks to spring apart to their full diameter. In testimony whereof I afiix my signature.
